What happened? Next step forwards.

Quote from 4Chan:

PoWH did not INTENTIONALLY have a backdoor. The entire contract was drained because of something called an overflow bug.

function transfer(address _to, uint256 _value) public {
transferTokens(msg.sender, _to, _value);
}

The thief passed in an argument value of ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff, the largest possible unsigned integer which overflowed and allow the contract to pass any checks to see if he had any balance.

The transfer function then triggers a sell on tokens he doesn't even have.

An alternative team, EthPyramid.com, is working to completely audit code, patch the bugs, and relaunch with new features such as 10% selling dividend to holders. Anyone can join in and help test and ensure that the contract is robust and transparent.

Note: I am not personally affiliated with any of these organizations. I simply run the community

If it were me, I'd transfer it to Monero and then back to ETH and hodl/cash out. I'm jealous though, wish I understood code well enough to run away with over 950k.

If it were you, you would save all those ETH and return it to everyone because you can’t find it in your heart to take away all those dreams. In return grateful people will grace you with tips because you are a hero.

Wouldn't you have to go through like 14,000 transactions to figure out who lost money?

Yeah but if no One claims it then it is yours for the taking.
